BATTERY-TESTING- LAlvIP.

T 0 all whom it may concern:

Be it known that I, CARL L. MAnrrznN, a citizen of the United States,residing in the city and county of San Francisco and State ofCalifornia, have invented a new and useful Improvement in a.Battery-Testing Lamp, of which the following is a specification. 1 c

My invention relates to a new article of manufacture comprising astorage battery testing lamp wherein two legs of a tripod operate asconductors to engage the terminals of a battery and to convey currentfrom the same to light the lamp and to position the same directlyoverthe'opening of I 'fibreor other dielectric material, around the saidbattery to illuminate the interior of the same and at the same timerender said interior or opening accessible for refilling and otherpurposes. I

The primaryfobject of the present invention is to provide a new andimproved article of manufacture arranged to facilitate the examination,testing and refilling of storage batteries and the like.

A further object of the invention is to provide a new and improvedarticle of manufacture of the character described adapted to directlight rays into the opening of a storage battery in such a manneras tofacilitate the examination terior of said battery. I

A still further object is to provide a new and sim'pledevice of thecharacter described which shall be arranged to draw current from thebattery being examined for the of the inpurpose of illuminating theinterior thereof,"

thereby eliminating a separate dry cell to light the lamp. I v I It isalso an object to provide a simple, cheap and effective device adaptedto contactwiththeterminals 01", a storage battery and to support a lightat an angle to the opening and slightly to one sidethereoi to rendersaid opening accessible for examination and refilling purposes.

I accomplish these and other objects by means of the improved devicedisclosed in the drawings forming a partot' the present specificationwherein like characters of reference are used to designate similar partsthroughout the said specification and drawings, and in which- Fig. 1 isa broken sectional view of a portion of one cell of a storage batterydisclosin my invention applied thereto;

Tig. 2 is a broken detailed view, partly Specification of LettersPatent.

1. i aha cam, t. Manrrzniv, or SAN rnanci'sco, canrronnra;

two legs of the tripod are connected to the lamp and arranged asconductors therefor. Fig. 3 is a side elevation of Fig. 1. Referring tothe drawings, the invention consists of a tripod comprising a handle 1of dielectric material, preferably wood.

The handle 1 is bored centrally at its lower end as at 3 withinwhichbore is inserted a metallic cap 4:terminating in a leg 6 having itslower end pointed as at 7 to facilitate contact with oneterminal 8 ofone cell of'a storage battery'9, as disclosed in Fig. 1 of the drawings.

Seated within the cap 4 is a sleeve 'llof lower end of which ismo'untedthe reflector 2 arranged to rece ve an electric lamp 12 whichscrewsgthrough the reflector. 2 and into the sleeve 11, therebycontacting the sleeve of said lamp 12 with nidl'efiector The legs '6 and14 are thus arranged as conductors to convey current from the hate tery9 to the lamp 12,'t he connection from the leg G being had through themetal cap 4-, and a spring 18 interposed between said cap 4 and the tipof the lamp 12.

A dielectric leg 19 is pivotally connected to the upper end of thehandlel as at 20 and is arranged to be setto'jsupportthe said handle 1and lamp 12 therein at an angle to the battery9so that access maybe hadto Patented lilay 9, 1922. Application filed January 22, 1921. SerialNo. 439,284.- i

the'central opening 21while illuminatedby said lamp, as disclosed inFig. 3 of the drawings. I I i v The leg 19 is pivotally connected sothat the handle 1 and lamp 12 therein may be,

supported at any convenient angle to said battery 9 and also to permitfolding of said leg 19 adjacent the handle 1 when not in use, asdisclosed in dotted lines in F 8 of the drawings.

In operation the cap, not shown, is unscrewed from the opening 21 andthe points 7 and16 of the legs 6 and 1 1, respectively, are driven orpressed into the terminals 8 and 17 so as to penetrate any grease, oilor other non-conducting accumulationof debris which may have formed uponsaid terminals, thereby insuring proper contact and passage ofelectrical current from the battery 9 to the lamp 12, thereby lightingsaid lamp and illuminating the interior f the a t y ,9

"to direct through said opening 21. The leg 19 is then positioned tosupport the tripod in the desired angle so that there will be no directreflection of the light rays from the lamp from the surface of theelectrolyte within the cell; thereby facilitating examination of theinterior of said cell.

The legs 6 and 1a are spaced to position the lamp 12 midway between saidlegs so as todirect light from said lamp directly into thcopening 21which is also arranged in standard batteries, midway between theterminals.

The angular disposition of the tripod and its lamp 12 also facilitateaccess through I said opening 21. whereby a syringe or.other instrumentor, tool may be readily inserted without interfering with the device.

Havingthus described my invention what I claim as new and desire tosecure by Letters Patent is'- y 1. A new article of manufacturecomprising atripod two legs thereof being conductors-and spaced toengagethe terminals of a storage battery and the like; and an electric lampconnected to said legs and lighted by current from said battery passingthrough said legs said lamp being positioned light rays into the openingof said battery. g

2. A new article of manufacture comprising a dielectric handle; an.electric lamp mounted upon the handle; and electrical terminalsconnected to thelamp and handle and arranged to contact with theterminals of "a storage battery'to convey current to said lamp from saidbattery and to position said lamp over the opening of said batterywhereby the interior of the samemay be illuminated. v I

3. A new article of manufacture comprising a dielectric handle; anelectric lamp mounted upon the handle; and electrical terminalsconnected to the lamp and handle and arranged to contact with theterminals of a storage battery to convey current to said lamp from lampover the opening of said battery whereby the interior of the same may beilluminated; and means for supporting said handle and lamp at an angleto said opening to render the same accessible.

4. A new article of manufacture comprising a dielectric handle; an.electric lamp mounted upon the handle; and electrical'terminalsconnected to the lamp and handle and arranged to'contactwiththejterminals of a storage battery to convey current to said lamp fromsaid battery and to position said lamp over the opening of said batterywhereby the interior of the same may be illumisaid battery and toposition said.
